Limestone, overlain by red and green flaggy sandstones. The 

 fossils recorded in the list on pp. 5-1:1-43, as coming from the 

 upper limestone-band at Whitfield, were found here. 



From the end of the Brinkmarsh-Parm ridge as far as a point 

 west of Tortworth-Court gas-works, a distance of about a mile, 

 no surface-indication can be found of the existence of the upper 

 limestone-band; but Mr. Harle informs us that it has been 

 proved by agricultural operations to extend for some distance to 

 the north-north-east of Whitfield farm. N'ear the gas-works 

 exposures are again met with, and at one point which appears to 

 correspond with the position of Barber's Quarry in Buckland & 

 Conybeare's map, the limestone dips eastwards at 50°. Sanders's 

 map shows an area of limestone at Brook Farm, but no trace can 

 now be found of its presence. The Sedgwick Museum contains a 

 small series of fossils from Barber's Quarry. 



A small ridge of limestone, with poor exposures from which we 

 obtained no fossils, lies close to the right bank of the stream 

 north-east of Falfield water-mill. 



(c) The Daniel's-Wood and Tortworth areas. — As has 

 been already mentioned, the region west and south-west of 

 Daniel's Wood shows three parallel limestone-ridges — the third 

 being possibly a repetition of the second by faulting or folding. 

 The westernmost, that of Heneage Court and Skeay's Grove, has 

 been already described ; the second, which commences by the stream 

 a quarter of a mile due north of Brook Farm, shows two distinct 

 lithological types — a flaggy micaceous sandstone, and underlying it 

 a peculiar, highly-fossiliferous, coarsely-crystalline limestone with 

 many little mud-pans, occasional grit-pebbles, abundant fragments 

 of horny brachiopods, and a considerable number of other fossils.'- 



Little Daniel's Wood, near the right bank of the stream, stands 

 on the third of these parallel ridges. About the middle of its 

 western margin are poor exposures of sandy crinoidal limestone 

 dipping at 25° in a south-easterly direction. We found a con- 

 siderable number of fossils here, and others in crinoidal limestone 

 and in calcareous sandstone which is poorly exposed at the southern 

 end of the wood (see list, pp. 541-43). 



There is also an exposure of limestone near the north-eastern 

 corner of the wood, where the dip is 30° E. 20° S. ; here we 

 found Calymene Blumenhaclii. 



Through the kindness of the Earl of Ducie a series of trenches 

 was dug on the slope of the hill south of Little Daniel's Wood. 

 The positions of these are shown in the plan (fig. 4, p. 529). 



2^0. 1 — the southernmost, entered Old Red Sandstone at a depth 

 of a foot, and was carried to a depth of nearly 5 feet without 

 reaching any other material. 



^ [Since the reading of our paper, the cutting of additional sections has 

 proved the presence of ashy particles in this deposit ; it becomes therefore 

 comparable with that at Cullimore's Quarry, and may be of the same (that is, 

 Llandovery) age.]
